Abstract We investigated whether a history of endoscopic tumor ablation impacts oncologic outcomes after radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UTUC). Using a multi-institutional database that contained patients who were treated with RNU, oncologic outcomes were assessed according to history of ureteroscopic tumor ablation. Disease-free survival (DFS) and...
Despite widespread use of dietary supplements, little is known about correlates and determinants of their use. Using a diverse sample from 7 interventions participating in the Behavior Change Consortium (n = 2539), signal detection methodology (SDM) demonstrated a method for identifying subgroups with varying supplement use. An SDM model was explored with an exploratory half of the entire sampl...

Clinical Studies Hemodynamic Mechanisms of Adaptation to Chronic High Sodium Intake in Normal Humans
The long-term hemodynamic effects of a high dietary sodium intake were studied in 10 young normal subjects. After a 4-day diet of 10 mEq of sodium and 60 mEq of potassium per day the mean arterial blood pressure (MAP) was 82.3 ± 15.1 mm Hg, the cardiac index (CI) was 2.32 ± 0.69 liter/min/m, and total peripheral resistance (TPR) was 1778 ± 947 dyne sec cm". After 4 to 6 days of 200 mEq of sodiu...
